Proposal: Update docs/reference/session_model.md

What Changed in the Implementation

Merged PR #3461 (fix(session): correct field names and data types in Session.as_cli_dict() for spec compliance) introduced two significant changes to the Session domain model in src/cleveragents/domain/models/core/session.py:

  1. New LinkedPlan value object — A new Pydantic model LinkedPlan was added with fields plan_id, phase, and state. This enables as_cli_dict() to emit spec-compliant linked_plans objects (with phase and state) rather than a flat list of IDs.

  2. New automation field on Session — The Session model gained an automation: str | None field to store the automation profile name associated with the session. This is surfaced in as_cli_dict() under session_summary.automation.

  3. Dual linked-plan storage — The Session model now has both:

    • linked_plan_ids: list[str] — flat list for persistence/backward compat
    • linked_plans: list[LinkedPlan] — rich objects with phase/state for CLI display

What Spec Sections Need Updating

docs/reference/session_model.md — Key Classes table

Current text (lines 9–14):

| Class | Description |
|-------|-------------|
| `Session` | Core session model with messages, token tracking, and export |
| `SessionMessage` | A single message within a session (ULID-identified, sequenced) |
| `MessageRole` | Enum: `user`, `assistant`, `system`, `tool` |
| `SessionTokenUsage` | Accumulated input/output token counts and cost |

Proposed text:

| Class | Description |
|-------|-------------|
| `Session` | Core session model with messages, token tracking, and export |
| `LinkedPlan` | Value object for a plan linked to a session, with `plan_id`, `phase`, and `state` |
| `SessionMessage` | A single message within a session (ULID-identified, sequenced) |
| `MessageRole` | Enum: `user`, `assistant`, `system`, `tool` |
| `SessionTokenUsage` | Accumulated input/output token counts and cost |

docs/reference/session_model.md — Export Serialization Order

Current text (lines 34–37):

schema_version, session_id, actor_name, namespace, messages,
linked_plan_ids, automation_level, token_usage, metadata,
created_at, updated_at, checksum

Problem: automation_level is a stale field name. The implementation's as_export_dict() does not include an automation or automation_level field in the export dict (the automation field is only surfaced in as_cli_dict() for display). The export dict contains exactly: schema_version, session_id, actor_name, namespace, messages, linked_plan_ids, token_usage, metadata, created_at, updated_at, checksum.

Proposed text:

schema_version, session_id, actor_name, namespace, messages,
linked_plan_ids, token_usage, metadata,
created_at, updated_at, checksum

Rationale

  • The LinkedPlan class is a first-class domain model that should be documented in the reference table.
  • The automation_level field name in the serialization order is stale — it was never in the implementation and does not appear in as_export_dict(). Removing it prevents confusion for implementors.
  • The automation field (added to Session) is intentionally not in the export dict (it's a display-only field for as_cli_dict()), so the export order should not include it.

Scope

  • File affected: docs/reference/session_model.md only
  • Main spec (docs/specification.md): No changes needed — the spec's CLI output examples already correctly show automation in session_summary and linked_plans as objects with plan_id/phase/state.

Classification

This is a reference doc correction (stale field name + missing class entry). The implementation is correct and matches the main spec. The reference doc is out of sync.

Architect Guidance: Approved — Update Session Domain Model Reference

The Session domain model reference doc needs two corrections:

  1. Add LinkedPlan class — this is a real domain model used in the implementation that links sessions to plans. It should be documented.
  2. Fix automation_levelautomation_profile — the field was renamed to align with the Automation Profile concept. The reference doc still uses the old name.

Both are factual corrections to match the implementation. No architectural decisions are being changed.

Recommendation: Proceed with the update.

Issue triaged by project owner:

  • State: Verified — Valid reference doc correction. PR #3461 added LinkedPlan value object and automation field to Session. The reference doc's Key Classes table is missing LinkedPlan and the Export Serialization Order contains the stale automation_level field name.
  • Priority: Low — The implementation is correct and matches the main spec. This is a reference doc sync issue. Not blocking.
  • Milestone: v3.3.0 — Session domain model is a v3.3.0 feature area
  • Story Points: 1 (XS) — Add one row to the Key Classes table, remove automation_level from the serialization order
  • MoSCoW: Should Have — Accurate reference documentation prevents implementor confusion. The stale automation_level field name is specifically misleading.
  • Parent Epic: #351 (Plan A6-A8: Sessions + Config CLI) — session model documentation
